GIZ - Nexus perspective in the water sector

Advisory services to BMZ and BMU for international agenda setting

Regional

National

Local

Advice to governments for considering interdependencies between water, energy and agriculture in planning processes e.g. assist government on for policy coherence and Nexus-framework-conditions.

Large-scale implementation of innovative solutions e.g. agricultural water management, integrated water resources management in cities, solar-power desalination and irrigation.

Support coordination between river basin organisations and regional energy actors

GIZ provides advisory services for international agenda setting, primarily to two Federal Ministries BMZ and BMU. e.g. by formulating the German position in the Post 2015 – SDG discussion

Support supra-national and regional coordination e.g. between River Basin Organisations and Regional Water Actors

Objective: Improve the capacities of utilities in planning and implementing water loss reduction strategies.

through ... the PPP-facility and in collaboration with the bi-lateral water

programs by ...

improving the institutional framework for the sustainable implementation of Water Loss Reduction measures

developing water loss reduction strategies and actions plans establishing national and regional training centers for water loss

reduction (incl. training of local trainers) promoting exchange of experiences and knowledge

Countries included in the WaCCliM-Program

10.11.2014


Objective: Reduce the carbon footprint of water and wastewater companies by reducing the energy consumption

by… integrating measures for greenhouse gas reduction into the

operation of selected water and wastewater utilities in Mexico, Peru and Thailand

improving political and institutional framework conditions for the use and financing of greenhouse gas reduction measures

developing guidelines and information materials for improving the carbon footprint of water and wastewater utilities

disseminating the experiences from Mexico, Peru and Thailand worldwide through the network of the International Water Association (IWA)
